Description	This poison can be added to any normal drink. The poisoner must remain within sight of the drink to facilitate its effects, or request a referee to remain. If the drink is left unattended, the poison is assumed to have lost effectiveness. Drinking this potion causes the imbiber, unless they resist it with e.g. the Resist Poison skill, to lose the power to communicate. They will babble incoherently, unable to make themselves understood, until the duration expires. Even attempts to communicate by writing will fail, although they may communicate in abstract ways, e.g. by drawing images or performing charades.
